Cosmological parameters derived from the final (PR4) Planck data release

We present constraints on cosmological parameters using maps from the last Planck data release (PR4). In particular, we detail an upgraded version of the cosmic microwave background likelihood, HiLLiPoP, based…

Improved constraint on the primordial gravitational-wave density using recent cosmological data and its impact on cosmic string models

Abstract: (IOP) The production of a primordial stochastic gravitational-wave (GW) background by processes occuring in the early Universe is expected in a broad range of models. Observing this background would…
